参考http://wiki.apache.org/nutch/RunNutchInEclipse 一、环境准备 1、下载nutch2.3源代码 wget http://mirror.bit.edu.cn/apache/nutch/2.3/apache-nutch-2.3-src.tar.gz 或者下载正在开发中的最新版本 svn co https://svn.apache.org/repos/asf/nutch/bra

一、环境准备
1、下载nutch2.3源代码
wget http://mirror.bit.edu.cn/apache/nutch/2.3/apache-nutch-2.3-src.tar.gz或者下载正在开发中的最新版本
svn co https://svn.apache.org/repos/asf/nutch/branches/2.x
2、选择使用的数据库类型,以hbase为例
在conf/nutch-site.xml中增加以下属性:
storage.data.store.class org.apache.gora.hbase.store.HBaseStore Default class for storing data
3、在ivy/ivy.xml中增加与hbase相关的依赖项,此项本已存在,但被注释掉,将注释去掉即可
其中plugin.folders的值为$NUTCH_HOME/build/pluginshttp.agent.name My Nutch Spider http.robots.agents none plugin.folders /Users/liaoliuqing/0_Search/1_Nutch/1_Official/apache-nutch-2.3/build/plugins
5、执行ant eclipse
二、导入project
1、导入project
三、运行程序
1、Run as ----> Run configuration,选择project与主类
2、填写参数
/Users/liaoliuqing/Downloads/seed.txt
-Dhadoop.log.dir=logs -Dhadoop.log.file=hadoop.log
3、点击run,输出结果如下:
InjectorJob: starting at 2015-01-28 16:27:43
InjectorJob: Injecting urlDir: /Users/liaoliuqing/Downloads/seed.txt
InjectorJob: Using class org.apache.gora.hbase.store.HBaseStore as the Gora storage class.
InjectorJob: total number of urls rejected by filters: 0
InjectorJob: total number of urls injected after normalization and filtering: 1
Injector: finished at 2015-01-28 16:27:47, elapsed: 00:00:04
注意,在运行程序前,本机需要先启动hbase。
4、查看hbase中的数据
hbase(main):003:0> scan 'webpage' ROW COLUMN+CELL com.163.www:http/ column=f:fi, timestamp=1422433667377, value=x00'x8Dx00 com.163.www:http/ column=f:ts, timestamp=1422433667377, value=x00x00x01K/xA7:x14 com.163.www:http/ column=mk:_injmrk_, timestamp=1422433667377, value=y com.163.www:http/ column=mk:dist, timestamp=1422433667377, value=0 com.163.www:http/ column=mtdt:_csh_, timestamp=1422433667377, value=?x80x00x00 com.163.www:http/ column=s:s, timestamp=1422433667377, value=?x80x00x00 1 row(s) in 0.2970 seconds

没有找到主方法吧你试试在目录里找到有main方法的类右键执行
